“My vehicle will not go but about 30 or 40 maybe 50 on highway after very slow exelaration I'm almost killed every time I get on the highway highway and reg streets to excearate it very very slow to start then I have to pull over and kill it start over not using het or air now it just won't start have not had it checked can't afford it”
NHTSA complaint #11280513, filed 2019-11, 100,000 miles“The odometer stopped working one (1) mile short of 300,000. Toyota told me that for that year and model car, the odometer was made to reach 299,999 only. They can replace it with new, that will start at 0 mile, but I will have to pay for it. This is unfair. They sold me a car that only reaches 299,999 and if I any to see the odometer reach a higher number, I must pay for it.”
NHTSA complaint #11253547, filed 2019-09, 299,999 miles“Since about the fall of last year or so, we've been noticing that the headlights have been going off intermittently. The right went out and then came back on. Then another time the left went out and came back on. I've read about this occurring on many other Prius' and that there was a class action suit? Anyway, I need to figure out how to get this fixed as it is a serious safety issue.”
NHTSA complaint #10493535, filed 2013-01, 135,000 miles“The car was initially swerving (as if in a bad wheel alignment). Then it took a sharp right turn and jumped off of the freeway. Despite my attempts to control it and keep it on freeway, due to the speed and momentum, it drove off the slope to the right of the road, rolled over and eventually landed right side up. Initially I thought it could be a blown up tire.. But that did not seem to be the case.”
NHTSA complaint #10542344, filed 2013-09, 105,000 miles“My 2005 Toyota Prius arbitrarily lost braking ability as I approached a ramp to enter another highway. Many lights went on including the red triangle with an exclamation point. I used the emergency brake to stop the car. I have been told that the skid control unit is broken and needs to be replaced. I will need to replace this part at a cost of $2200. Is this unit a safety threat?”
